the lower quadrant of the guide bar to avoid climbing
kickback.
Pinching kickback
Pinching is when the cut closes and pinches the cutting
equipment. If the diamond chain is pinched or stalled the
reactive force will be strong and you might not be able to
control the power cutter.
If the diamond chain is pinched or stalled in the kickback
zone, the reactive force will push the power cutter up
and back towards the user in a rotating motion causing
serious or even fatal injury. Be alert for potential
movement of the work piece or anything else that can
occur, which could cause the cut to close and pinch the
cutting equipment.
To cut in pipes
WARNING: If the diamond chain is pinched
in the kickback zone it will cause a severe
kickback.
Special care should be taken when cutting in pipes. If
the pipe is not properly supported and the cut kept open
through out the cutting, the guide bar might be pinched.
Be especially alert when cutting a pipe with a belled end
or a pipe in a trench that, if not properly supported, may
sag and pinch the guide bar.
If the pipe is allowed to sag and close the cut, the guide
bar will be pinched in the kick back zone and a severe
kick back might develop. If the pipe is properly
supported the end of the pipe will move downward, the
cut will open and no pinching will occur.
1. Secure the pipe so it does not move or roll during
cutting.
2. Cut section "I" of the pipe.
I
III II
3. Ensure that the cut opens to avoid pinching.
4. Move to side II and cut from section I to bottom of
the pipe.
5. Move to side III and cut the remaining part of the
pipe ending at the bottom.
To prevent a kickback
WARNING: Avoid situations where there is a
risk of kickback. Take care when using your
power cutter and make sure that the
diamond chain is never pinched in the
kickback zone.
WARNING: Be careful when you put the
diamond chain in an existing cut.
WARNING: Make sure that the work piece
cannot move during a cutting operation.
